Try this:

applet.append("");  // Append a blank string to fix Issue 73
applet.append64("QTU5MCwxNjAwLDIsMywxLDEsTiwialplYnJhI...");

This is because to save on resources, I don't initialize PrintRaw until it's 
needed using the "getPrintRaw()" method.

public void append(String s) {
 getPrintRaw().append(s);
}

public void append64(String s) {
 printRaw.append(Base64.decode(base64)); // Should be getPrintRaw().append(Base64.decode(base64));
}

Should be fixed in the next version.  Sorry for the inconvenience.
